Homeostasis, growth and reproduction in crustaceans are under endocrine control as is established in other animals. The identification of crustacean hormones and elucidation of mechanisms of hormonal regulation have been pursued extensively. Mechanisms are found to be partly similar to, but also considerably different from those in insects, although both groups of animals are arthropods. Moltin...

The cytological features including chromosome numbers and detailed measurements of 46 populations ten Achillea species ( A. aleppica, bibersteinii, eriophora, filipendula, millefolium, nobilis, pachycephala, tenuifolia, vermicularis, wilhelmsii ) were reported from Iran. Sample plants seeds collected diff erent geographical regions Total length, long/ short arm ratio, centromere index, total fo...

M. Dudek, AGH University of Science and Technology, Krakow, Faculty of Management, Poland In the blast-furnace production, raw materials may account for approx. 50 % of the pig-iron manufacture costs. Therefore, any, even small, saving in the sphere of raw material purchasing will translate into the reduction in the cost of the pig-iron manufacture. The selection of appropriate supply sources a...

Ultraviolet photodissociation (UVPD) mass spectrometry is employed to investigate the structure of holo-myoglobin as well as its apo form transferred to the gas phase by native electrospray. UVPD provided insight into the stability of native structural elements of holo-myoglobin. The fragmentation yields from UVPD showed the greatest overall correlation with B-factors generated from the crystal...
